The Ada Semantic Interface Specification (ASIS) is an interface between an
Ada environment as defined by ISO/IEC 8652 (the Ada Reference Manual) and
any tool requiring information from this environment. An Ada environment
includes valuable semantic and syntactic information. ASIS is an open and
published callable interface which gives CASE tool and application
developers access to this information. ASIS has been designed to be
independent of underlying Ada environment implementations, thus supporting
portability of software engineering tools while relieving tool developers
from having to understand the complexities of an Ada environment's
proprietary internal representation.
ASIS 95 is the ASIS interface to Ada 95 (ISO/IEC 8652:1995).
ASIS 95 is now available as ISO/IEC 15291:1999.

textproc/xmlada: Upgrade version 4.6.0.0 => 17.0.0 (scheme change)
The numbering scheme changed to presumably match years (e.g. 17 => 2017)
Bump everything with a build dependency as there is a matching soname
change. Everything still builds on a DF exp-run.

Change Ada Framework foundation from gcc5-aux to gcc6-aux
GCC 6.1 was released this week. The Ada Framework in FreeBSD ports has
been based on GCC 5.3 GNAT although GCC 6.x has been supported for awhile
via the ADA_DEFAULT option in make.conf.
Now that GCC 6 has been officially released, switch to it by default.
People can maintain the old foundation by putting "ADA_DEFAULT=5" in
/etc/make.conf.
Libraries built by one GNAT are unusable by another, so almost every Ada
port has been bumped as a result. Noticable exceptions are dns/ironsides
which fails to build on gcc6 (thus USES=ada:5 is set) and cad/ghdl which
needs additional testing as it may require gcc5 on FreeBSD (DragonFly
uses the LLVM backend only).

lang/asis: Fix build for gcc6
The UET_Address attribute has been removed for gcc6. It was intended for
internal use only, but it wasn't used. Rather than apply this patch for
GCC6 only through the EXTRA_PATCHES mechanism, just unconditionally remove
the check regardless of gnat used to build it. (It should not make any
difference). No bump required.

Ada Framework: Switch to gcc5-aux, upgrade 6 packages at once
The transition from gcc-aux to gcc5-aux in the Ada framework has been
blocked by the inability to build gtkada3 and, once resolved, GPS (due
to tight locking with compiler).
A few days ago, Adacore made their annual release of their main libre
products, include GPS. However, some products were tightly coupled with
the recent compilers, so in order to upgrade, the compiler had to be
switched and dependencies require many ports to be upgraded at once:
* lang/asis
* devel/gnatcoll
* devel/gps
* x11-toolkits/gtkada3

textproc/xmlada: Upgrade version 4.5.0.0 => 4.6.0.0, overhaul make system
Due to the unavailability of a public repository, this version uses
Adacores 2015 distribution of xmlada. It's probably a minor update
from the previous one.
The major change, however, is the creation of a custom makefile to build
and install xmlada. Why? because gnatmake will lose the ability to
build project files in the near future, so xmlada makefiles were changed
to use gprbuild to build and itself it. One problem: gprbuild needs
xmlada as a build dependency. (and it also needs gprbuild to build
itself!!) I could have chosen to keep using gnatmake, but I decided to
bite the bullet, fix it correctly now and not have to get stuck by it
by future versions of gnat that remove project management from gnatmake.

lang/asis: Fix build on gcc5-aux
The OpenVMS support was removed on gcc5's GNAT so the GPL 2014 version
of ASIS won't build unless the references to OpenVMS are removed. Rather
than use EXTRA_PATCHES, just remove them unconditionally. This doesn't
cause any issue for gcc-aux-built ASIS and the ports that use it.

lang/asis: New version as result of gcc-aux upgrade to gcc49
The ASIS source has to be matched with the compiler source of the compiler
that builds it. ASIS is always tricky because it's matched to annual
releases of GNAT GPL, and never to GNAT FSF. However, after disabling the
useless (and faulty) strong version check, ASIS 2013 seems to work okay
with gcc49. At least the two ports that use it seem to work ok.

Tie libgnat_util.a to libasis
Rather than specify gnat_util every time ASIS is a dependency, set it
as a library dependency for ASIS. LIB_DEPENDS doesn't work because it
is a static library, so just manually add libgnat_util.a to BUILD_DEPENDS
and RUN_DEPENDS, then adjust 3 ports accordingly.

Add new port: lang/asis
This is ASIS, the Ada Semantic Interface Specification.
ASIS is tightly coupled with lang/gcc-aux and must be built with the same
sources. For this reason, ASIS will not work with other Ada compilers,
including GNAT GPL (lang/gnat).
ASIS is a dependency of several upcoming Ada ports.
